3-1-1 Installation and Wiring Precautions
Be sure to consider the following factors when installing and wiring the FQM1
to improve the reliability of the system and make the most of the FQM1’s func-
tions.
Ambient Conditions Do not install the FQM1 in any of the following locations.
• Locations subject to ambient temperatures lower than 0
°C or higher than
55 °C.
• Locations subject to drastic temperature changes or condensation.
• Locations subject to ambient humidity lower than 10% or higher than
90%.
• Locations subject to corrosive or flammable gases.
• Locations subject to excessive dust, salt, or metal filings.
• Locations that would subject the FQM1 to direct shock or vibration.
• Locations exposed to direct sunlight.
• Locations that would subject the FQM1 to water, oil, or chemical reagents.
Be sure to enclose or protect the FQM1 sufficiently in the following locations.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power lines.
Installation in
Cabinets or Control
Panels When the FQM1 is being installed in a cabinet or control panel, be sure to pro-
vide proper ambient conditions as well as access for operation and mainte-
nance.
Temperature Control The ambient temperature within the enclosure must be within the operating
range of 0
°C to 55°C. When necessary, take the following steps to maintain
the proper temperature.
• Provide enough space for good air flow.
• Do not install the FQM1 above equipment that generates a large amount
of heat such as heaters, transformers, or high-capacity resistors.
• If the ambient temperature exceeds 55
°C, install a cooling fan or air con-
ditioner.
Accessibility for
Operation and
Maintenance • To ensure safe access for operation and maintenance, separate the
FQM1 as much as possible from high-voltage equipment and power
equipment.
